Answer: Option (a) is the correct answer.

Explanation:

In gaseous state, molecules move rapidly from one place to another as the molecules have high energy.

So, when gaseous state changes into liquid state then molecules slow down in speed because of decrease in energy molecules come slightly closer to each other.

For example, during condensation of water, vapors change into liquid.

Thus, we can conclude that energy must be removed because particles in liquid move more slowly best describes the transition from gas to liquid.

PAP Physical Studies<br><br> How can you remember the periodic table?

siniylev [52]

Break down the table into smaller sections. Memories period by period or if you like by group (like halogens or noble gases).
Just say the elements in order everyday 1-10 then when you get those 11-20 and continued.

In general, which attractions are stronger: intermolecular or intramolecular? Research and explain a quantitative comparison bet

murzikaleks [220]

Answer is: intramolecular attractions are stronger.

Intramolecular attractions are the forces between atoms in molecule.

There are several types of intramolecular forces: covalent bonds, ionic bonds.

Intermolecular forces are the forces between molecules. The stronger are intermolecular forces, the higher is boiling point of compound, because more energy is needed to break interaction between molecules.

There are several types of intermolecular forces: hydrogen bonding, ion-induced dipole forces, ion-dipole forces andvan der Waals forces.

Hydrogen bonds are approximately 5% of the bond strength of covalent C-C or C-H bonds.

Hydrogen bonds strength in water is approximately 20 kJ/mol, strenght of carbon-carbon bond is approximately 350 kJ/mol and strengh of carbon-hydrogen bond is approximately 340 kJ/mol.

20 kJ/350 kJ = 0.057 = 5.7 %.

Help me please someone help me I’ve been here for hours

mash [69]

Answer:

Eukarya- Multicellar and unicellar

Explanation:

Fugi- Multicellar

Protista- unicellar

eubacteria- unicellar and have no nucleus

Eukarya is the only option, and that is because Eukarya is both! It contains a nucleus, and a membrane making it the only one that fits into the incomplete graphic! Hope this helps! (I noticed you were waiting for a while so I came to help! <3)

Write the net ionic equation for the reaction between hydrochloric acid and potassium cyanide. Do not include states such as (aq

zhannawk [14.2K]

Answer: $H^++CN^-\rightarrow HCN$ , product favoured

Explanation:

Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.

Net ionic equation : In the net ionic equations, we do not include the spectator ions in the equations.

When hydrochloric acid react with potassium cyanide, then it gives potassium chloride and hydrocyanic acid as products.

The complete ionic equation will be:

$H^++Cl^-+K^++CN^-\rightarrow K^++Cl^-+HCN$

The net ionic equation will not contain spectator ions which are $K^+$ and $Cl^-$ :

$H^++CN^-\rightarrow HCN$

The reaction is product favoured.
